Definitions

  • the present invention belongs to the area of cosmetic and household applications and refers to improved stabilization of cosmetic and household formulations by addition of a mixture comprising at least a phenyl alkanol and at least a linear alcohol.
  • cosmetic compositions comprise a multitude of components. Looking at the listing of ingredients for an average night cream one can find up to 20 positions and there has been a tendency to add as many ingredients as possible in order to address many different issues, all at the same time. As a matter of fact, many consumers equal complexity of a composition with benefit and are accepting high prices, since (s)he expects also high performance. On the other hand, the more complex a composition becomes, the more difficult it is to avoid negative interactions between the components.
  • a major problem for cosmetic compositions of course in particular for all types of emulsions, is still their stability, especially in case they are subjected to difficult storage conditions, like high or low temperatures. An improved emulsion stability can be achieved by reducing the oil droplets of emulsion.
  • Another object is related to the sensorial profile. Spreadability, afterfeel and smell are important parameters contributing to the overall liking of a cosmetic formulation after application to skin:
  • Another problem especially for shampoo compositions is foam stability and viscosity.
  • Example 1 discloses a composition comprising 1 to 4 % 4-MAP in combination with oil bodies, emulsifiers and actives.
  • a further aspect refers to fragrances.
  • Cosmetic and household products are often perfumed to meet the requirements of the consumers.
  • the important functions of fragrances are to provide pleasant odours, to mask the base smell of the product, and also to give the product an odour identity.
  • fragrances are usually poorly water-soluble or insoluble compounds it is often difficult to perfuming the products.
  • the use of emulsifiers and surfactants is nowadays a standard solubilisation technique to improve the solubility of fragrances in preparations and formulations.
  • their use as solubilizing agents often leads to further different problems, such as causing cloudiness and turbidity in transparent formulations, skin irritation, and sensitization to light.
  • Another big problem in the use of fragrances in products is their high loss rate and the rapid decreases during storage due to volatilization, evaporation, oxidation and poor stability.
  • a further substance class which shows the same solubility problems in cosmetic and household products like fragrances and flavors, are lipophilic compounds.
  • a large number of lipophilic molecules have very low solubility in (cosmetic) solvents and have a tendency to recrystallize or separate rapidly.
  • DHEA Dehydroepiandrosteron
  • DHEA Dehydroepiandrosteron
  • block copolymers do not satisfactorily dissolve the lipophilic compound.
  • the object of the present invention has been to identify a multi-functional additive for cosmetic and household formulations, which does not negatively interact with other ingredients while improving the stability, in particular in aspects of viscosity, foam stability, concerning soap bars the cracking stability and in overall the sensorial profile of the cosmetic or household compositions/formulations containing this additive.
  • the invention further objects to identify an additive which, in particular, have the mentioned properties in regard to flavors and fragrances and at the same time show additional improving characters concerning the solubility of lipophilic components in general, e.g. plant oils, neutral oils and fatty acid esters, especially in water-ethanol based or water-based formulation, and thus contribute to avoidance of phase separation and instability of the compositions/formulations.
  • an additive which, in particular, have the mentioned properties in regard to flavors and fragrances and at the same time show additional improving characters concerning the solubility of lipophilic components in general, e.g. plant oils, neutral oils and fatty acid esters, especially in water-ethanol based or water-based formulation, and thus contribute to avoidance of phase separation and instability of the compositions/formulations.

  • Example 1 emulsion stability
  • O/W emulsions were prepared by heating a lipid phase A and an aqueous phase B separately to approximately 80 °C. Then the aqueous phase B was added to the lipid phase A and mixed by using an Ultra-Turrax stirrer for 2 minutes at 5.000 rpm. The emulsion thus obtained was allowed to cool down for 10 minutes using a vane stirrer at 150 rpm. Finally, the pH value was adjusted to about 6.0.

  • the tests were performed 1 day after preparation of the emulsions A and B.
  • Figure 1 and figure 2 are images of cuvettes containing emulsions A and B after centrifugation process.
  • Emulsion B (containing 0.8 % 1-dodecanol and 0.2% 2-benzylheptanol) showed less water separation in comparison to emulsion A (without active) and therefore improved stability after centrifugation according to the method described above. Furthermore the instability index of emulsion B (containing 0.8 % 1-dodecanol and 0.2% 2-benzylheptanol) is much lower versus instability index of emulsion A, which also indicates improved stability.
  • Emulsion B (containing 0,8 % 1-dodecanol and 0,2% 2-benzylheptanol, see Figure 4 ) showed smaller oil droplets (particle sizes) in comparison to emulsion A (without active see Figure 3 ). Smaller oil droplets indicate a more homogeneous appearance and better stability of the emulsion.
  • Shampoos were prepared with the following production method according to the shampoo formulation of table 3: Blend Phase A by stirring slowly with a vane stirrer, stop the process when foaming starts. Swell Ucare Poylmer JR-400 in water by stirring and warming up to 50°C.

Lower drainage formation indicates improved foam stability and structure for a longer time. The values of liquid drainage in ml were depicted on the y-axis.
